TOOL

Application filed November 23, 1923.

gf', 'iff/0my it may concern:

.lie it known that I, lloninrr Morrrr'r, a citizen of theV UnitedStates, and a resident of Cincii'inati. in the county of Hamilton andState of tlhio, have invented certain new and useful linpriiwements in'Tools, of which the 'following is a full, clea'r, and exact deriptioinreference being` `rad 'to' the accompanying drawing, forming part ofthis specification.

My invention relates to improvements in monkey wrenches, in which thesmooth faces of the wrench aws can be readily and easily converted intoserrated jaws to serve as a pipe wrench, and in which the tool isprovided with a collapsible frame for mounting a hacksaw, with the bladeadapted to be tightened by the ordinary adjustment of the movable `jawof the wrench.

The invention consists of that certain novel construction andarrangement of parts which will bc hereinafter more particularly pointedout and claimed, in which the above recited results and other featuresof novelty are attained .l n the drawing:

Figure 1 is a perspective view of my new tool;

llig. 2 is a similar view of the outer end of the handle portion of thewrench removed from the body of the handle;

Fig. 3 is a perspective view of the wrench jaws, serrated to serve as apipe wrench and partly in section; and

Fig. -l is a. similar perspective view with the hacksaw mounted on thewrench.

The main portion of the wrench is of ordinary construction with an outerfixed jaw 1 rigidly mounted on the end of the threaded shank 2. Theinner movable jaw 3 is mountcd to slide on the outer Unthreaded portionof the shank, and its shank portion d is cut away to receive thethreaded nut 5 traveling on the threaded shank 2, so that by turning thenut 5, the movable aw will be advanced or retracted as desired, tocooperate with the fixed jaw 1.

The inner face of the outer fixed jaw 1 is provided with a detachableplate 6, serrated on one side 7, with the serrations engaging similarserrations 8 on the fixed jaw- This plate 6 with the smooth sideoutermost is secured to the outer jaw 1 by a screw 9. The serrations arethus protected from wear and misuse. The` inner face of the movable jaw3 is provided with a threaded hole 10 to rc- 'senar No. 676,651.

ceive lth'e'screw 9, and when it is desired to provide serrated aws fora pipe' wrench the plate 6 is removed from the outer jaw, andtransferred to the4 movable aw with the serrations 'i' and 8 opposed to''each other, and the plate 6 is secured in this position by the screw'1`hus the smooth aws of the' wrench arev converted into serrated jawsas for a pipe wrench.

The movable jaw 3 on one face is providedE with a dovetailed groove 12,in which is mounted a sliding bar 13, with a pair of holes 1l, 15, and aspring-pressed pin 16 seated in a socket in the base of the groove 12,normally engages in the hole to retain the bar 13 in place. Bydepressing the pin 1G, the bar will be released and the bar can then beextended until the locking pin engages the hole 14. The other end of thebar carries a stud or pin 17 which is normally seated in a groove 18 inthe head of the movable jaw.

The shank 2 is fitted with a handle 20, and in a. groove 21 in thehandle is pivoted an arm 22 normally flush with the surface of thehandle. The pivot end of the arm 22 is formed with a shoulder 23 to holdthe arm when extended at right angles to the handle, and the end of thearm is bent at its outer end to form a supporting pin 24C in line withthe stud 17.

The upper face of the shank of the wrench is provided with a lengthwisegroove 25v which extends across the fixed jaw and into the handle 20,and in this groove a saw blade 25 is secured by a screw 26 which passesthrough a hole in the end of the blade and is threaded into a hole inthe shank. By removing the screw 26, the saw blade is released and canbe withdrawn by lifting its rounded outer end. The blade also has a holeat its opposite end to correspond with the screw hole and with the frameparts 13 and 22 extended; and the saw blade may be mounted on the studs17 and 24, and the blade drawn taut by adjusting the jaw 3 by the nut 5.

For holding the handle 2O on the shank, a long bolt 28 is provided witha disk 29 to abut against the end of the handle. This bolt isscrew-threaded at the end to screw into a threaded recess in the shank,and this end of the bolt is formed into a screw-driver 30 and the diskor head 29 serves to cover the stud 24 when the arm 22 is not in use.The outer end of the bolt 28 is formed in the shape of an alligatorWrench 31, which serves also as an extension of the handle when the sawis in use. The screw-driver 3() is of a size to it the screws 9 and 26.

Having thus described my invention, what I claim as new and desire toSecure b v Letters Patent, is

l. In a tool of the character speoiied, provided Wit-li an operatinghandle and a shank portion, a fixed outer jaw on said shank, and amovable inner jaw thereon, with means for adjusting and holding themovable jaiv with relation to the outer jaw, the movable jaw beinggrooved longitudinally with a slidable bar carrying a. projecting studseated in said groove, and an arm piv oted to the handle with acorresponding stud thereon, said bar and arm adapted to be projected toform a frame for a saw blade, with the jaw adjusting means adapt ed totighten said frame. l

2.1n a tool oi the character specified, provided with an operatinghandle and a shank portion, a fixed outer jaw on Said shank, and amovable inner jaw thereon, with means for adjusting and holding themovable jaw with relation to the outer jaw, the movable jaw beinggrooved longitudinally with a slidable bar seated in said groove, and anarm pivoted to the handle, n

with a longitudinal groove to receive and hold the saw blade.
